Welsh rugby coach Warren Gatland has his legs in casts after falling while cleaning windows at his Waihi Beach bach on Monday.
The New Zealander lost his balance about 8.30am and fell three metres onto concrete, taking the full impact on his heels, the Welsh Rugby Union said in a statement.
He suffered multiple fractures to the right calcaneus and also a fracture to the left calcaneus.
He is in leg casts and requires surgery to reconstruct his right heel at Waikato Hospital.
The WRU group chief executive, Roger Lewis, said although it could be several weeks before he fully recovers he is expected to be able to return to active coaching duties before his recuperation is complete.
